Funny how things come to you reading the Bible.
So Abraham the Hebrew, the father of ALL Israelites liked himself some milk.
And he (Abraham) took butter and milk, and the calf which he had dressed; and he set them before them (Sarah and Yahweh), and they did eat, and he stood by them under the tree.
(Genesis 18:8 Brenton)
Abraham, Sarah and Yahweh were NOT lactose intolerant.
and I said to you, Ye shall inherit their land, and I will give it to you for a possession, even a land flowing with milk and honey: I am the Lord your God, who have separated you from all people.
(Leviticus 20:24 Brenton)
If you use E-Sword you should find some 22-23 references to Yahweh giving his people a land full of MILK and honey.
That's an odd thing to do if ALL your people are lactose intolerant.
So we must assume that, Yahweh's people were NOT lactose intolerant.
So what's this then ?

Hmm I guess they must not be Yahweh's people!
